Quality Improvement Intervention Using Social Prescribing at Discharge in a University Hospital in France: Quasi-Experimental Study

BACKGROUND

Social prescription is seen as a public health intervention tool with the potential to mitigate social determinants of health. On one side, social prescription is not yet well developed in France, where social workers usually attend to social needs, and historically, there is a deep divide between the health and social sectors. On the other side, discharge coordination is gaining attention in France as a critical tool to improve the quality of care, assessed indirectly using unplanned rehospitalization rates.

OBJECTIVE

This study aims to combine social prescription and discharge coordination to assess the need for social prescription and its effect on unplanned rehospitalization rates.

METHODS

We conducted a quasi-experimental study in two departments of medicine in a French university hospital in a disadvantaged suburb of Paris over 2 years (October 2019-October 2021). A discharge coordinator screened patients for social prescribing needs and provided services on the spot or referred the patient to the appropriate service when needed. The primary outcome was the description of the services delivered by the discharge coordinator and of its process, as well as the characteristics of the patients in terms of social needs. The secondary outcome was the comparison of unplanned rehospitalization rates after data chaining.

RESULTS

A total of 223 patients were included in the intervention arm, with recruitment being disrupted by the COVID-19 pandemic. More than two-thirds of patients (n=154, 69.1%) needed help understanding discharge information. Slightly less than half of the patients (n=98, 43.9%) seen by the discharge coordinator needed social prescribing, encompassing language, housing, health literacy, and financial issues. The social prescribing covered a large range of services, categorized into finding a general practitioner or private sector nurse, including language-matching; referral to a social worker; referral to nongovernmental organization or group activities; support for transportation issues; support for health-related administrative procedures; and support for additional appointments with nonmedical clinicians. All supports were delivered in a highly personalized way. Ethnic data collection was not legally permitted, but for 81% (n=182) of the patients, French was not the mother tongue. After data chaining, rehospitalization rates were compared between 203 patients who received the intervention (n=5, 3.1%) versus 2095 patients who did not (n=51, 2.6%), and there was no statistical difference.

CONCLUSIONS

First, our study revealed the breadth of patient's unmet social needs in our university hospital, which caters to an area where the immigrant population is high. The study also revealed the complexity of the discharge coordinator's work, who provided highly personalized support and managed to gain trust. Hospital discharge could be used in France as an opportunity in disadvantaged settings. Eventually, indicators other than the rehospitalization rate should be devised to evaluate the effect of social prescribing and discharge coordination.

Risk Factors for 30-day Hospital Readmissions After Peripheral Vascular Interventions in Peripheral Artery Disease Patients at the US-Mexico Border

Peripheral artery disease (PAD) is associated with high rates of readmission following endovascular interventions and contributes to a significant hospital readmission burden. Quality metrics like hospital readmissions affect hospital performance, but must adjust to local trends. Our primary goal was to evaluate risk factors and readmission rates post-percutaneous peripheral intervention in a US-Mexico border city, at a single tertiary university hospital. We performed a retrospective review of patients with PAD undergoing first time peripheral intervention from July 2015 to June 2020. Among 212 patients, 58% were readmitted with median 235-day follow-up (inter-quartile range (IQR) 42-924); 35.3% of readmissions occurred within 30 days, and 30.2% of those were within 7 days. Median time to readmission was 62 days. Active smokers had 84% higher risk of readmission (hazard ratio (HR) 1.84, 95% CI 1.23-2.74, P < .01). Other significant factors noted were insurance status-Medicaid or uninsured (HR 1.94, 95% CI 1.22-3.09), prior amputation (HR 1.69, 95% CI 1.13-2.54), heart failure, both preserved (HR 4.35, 95% CI 2.07-9.16) and reduced ejection fraction (HR 1.88, 95% CI 1.14-3.10). Below the knee, interventions were less likely to be readmitted (adjusted HR .64, 95% CI 0.42-.96). Readmission rates were unrelated to medication adherence.

Does diabetes affect outcome or reoperation rate after lumbar decompression or arthrodesis? A matched analysis of the Quality Outcomes Database data set

OBJECTIVE

Diabetes mellitus (DM) is a known risk factor for postsurgical and systemic complications after lumbar spinal surgery. Smaller studies have also demonstrated diminished improvements in patient-reported outcomes (PROs), with increased reoperation and readmission rates after lumbar surgery in patients with DM. The authors aimed to examine longer-term PROs in patients with DM undergoing lumbar decompression and/or arthrodesis for degenerative pathology.

METHODS

The Quality Outcomes Database was queried for patients undergoing elective lumbar decompression and/or arthrodesis for degenerative pathology. Patients were grouped into DM and non-DM groups and optimally matched in a 1:1 ratio on 31 baseline variables, including the number of operated levels. Outcomes of interest were readmissions and reoperations at 30 and 90 days after surgery in addition to improvements in Oswestry Disability Index, back pain, and leg pain scores and quality-adjusted life-years at 90 days after surgery.

RESULTS

The matched decompression cohort comprised 7836 patients (3236 [41.3] females) with a mean age of 63.5 ± 12.6 years, and the matched arthrodesis cohort comprised 7336 patients (3907 [53.3%] females) with a mean age of 64.8 ± 10.3 years. In patients undergoing lumbar decompression, no significant differences in nonroutine discharge, length of stay (LOS), readmissions, reoperations, and PROs were observed. In patients undergoing lumbar arthrodesis, nonroutine discharge (15.7% vs 13.4%, p < 0.01), LOS (3.2 ± 2.0 vs 3.0 ± 3.5 days, p < 0.01), 30-day (6.5% vs 4.4%, p < 0.01) and 90-day (9.1% vs 7.0%, p < 0.01) readmission rates, and the 90-day reoperation rate (4.3% vs 3.2%, p = 0.01) were all significantly higher in the DM group. For DM patients undergoing lumbar arthrodesis, subgroup analyses demonstrated a significantly higher risk of poor surgical outcomes with the open approach.

CONCLUSIONS

Patients with and without DM undergoing lumbar spinal decompression alone have comparable readmission and reoperation rates, while those undergoing arthrodesis procedures have a higher risk of poor surgical outcomes up to 90 days after surgery. Surgeons should target optimal DM control preoperatively, particularly for patients undergoing elective lumbar arthrodesis.

Predictive Value of LACE Scores for Pediatric Readmissions

INTRODUCTION

Hospital readmissions are recognized as a prevalent, yet potentially preventable, personal and economic burden. Length of stay, Acuity of admission, Comorbidities, and number of Emergency Department visits in the preceding 6 months can be quantified into one score, the LACE score. LACE scores have previously been identified to correlate with hospital readmissions within 30 days of discharge, but research specific to the pediatric population is scant. The objective of the present study was to investigate if LACE scores, in addition to other factors, can be utilized to create a predictive pediatric hospital readmission model that may ultimately be used to decrease readmission rates.

METHODS

This study included 25,616 hospitalizations of patients under the age of 18 years. Data were extracted from a hospital network electronic medical record. Demographics included LACE scores, age, gender, race/ethnicity, median household income, and medical centers. The primary exposure variable was LACE score. The main outcome measures were readmissions within 7, 14, and 30 days. The area under the curve (AUC) was used to assess the predictive capability of the regression model on patient 30-day admission.

RESULTS

LACE scores, age, gender, race/ethnicity, median household income, and medical centers were examined in a multivariable model to assess patient risk of a 30-day readmission. Only age and LACE score were observed to be statistically significant. The AUC for the combined model was 0.69.

DISCUSSION

As only age and LACE score were observed to be statistically significant and the AUC for the combined model was 0.69, this model is considered to have poor predictive capability.

CONCLUSIONS

In this study, LACE scores, as well the other factors, had a poor predictive capability for pediatric readmissions.

Comparison of hospitalist service staffing models at Baylor University Medical Center

Background

Baylor University Medical Center benefits from being a quaternary care center with 900+ licensed beds and multiple different models to staff patients on the hospitalist service. These models include hospitalist only, resident teaching teams, and two different advanced practice practitioner teams. The primary goal of this study was to assess these different staffing models and to ascertain which model, if any, has better outcomes related to length of stay, total hospital charges, 30-day readmission rates, patient satisfaction, hospital-acquired infections, mortality, and early discharges.

Methods

The study was an observational retrospective chart review of all discharges from the hospitalist service at Baylor University Medical Center from October 1, 2021, to February 28, 2022. Patients were included if the hospitalist team was the primary team of record at the time of discharge. A total of 7803 patients were included.

Results

There was no difference in patient satisfaction, hospital-acquired infections, and mortality between the groups. The teaching teams had a shorter length of stay before the removal of outliers. Independent advanced practice practitioners reliably had more patients discharged before 11:30 am. Results support the concept of continuity of care, as well as lower patient-to-provider ratios.

Conclusions

These results have actionable implications that support the use of different advanced practice practitioner teams for the safe care of hospitalized patients as well as the safe integration of residents into patient care.

Impact of Podiatric Surgery Consultation for Foot and Ankle Wounds on Patient Outcomes in a Community Hospital

Previous studies have demonstrated that timely podiatric surgery consultation results in positive patient outcomes. However, there are limited studies focused on readmission rates in teaching community hospitals. The primary aim of this study is to determine if consulting podiatric services was associated with lower 30-day readmission rates and impact on length of stay in patients with lower extremity wounds. The secondary aim was to investigate medical and socio-economic factors associated with better outcomes. This study was a cross-sectional descriptive study. A retrospective chart review utilizing the hospital's electronic medical record system identified patients with lower extremity wounds (based on ICD-10 codes) admitted between July 2018 and December 2020. The results showed a 3-fold decrease in 30-day readmission rates in patients with podiatric surgery consultation compared to patients without consultation with lower extremity wounds (4.2% vs 11.3%, p = .03). Multivariate regression models showed patients with gangrene (AOR = 7.61; p = .04) or osteomyelitis (AOR = 9.07; p = .013) had a higher likelihood of readmission than patients with venous ulcer (reference category) after controlling for podiatric consultation. Among the group of patients with podiatric consultation, earlier podiatric consultations resulted in decreased length of stay. This study identifies prior amputation history and lack of podiatric consultation increased 30-day readmission rates.

Relationship Between In-Hospital Adverse Events and Hospital Performance on 30-Day All-cause Mortality and Readmission for Patients With Heart Failure

BACKGROUND

Hospitals with high mortality and readmission rates for patients with heart failure (HF) might also perform poorly in other quality concepts. We sought to evaluate the association between hospital performance on mortality and readmission with hospital performance rates of safety adverse events.

METHODS

This cross-sectional study linked the 2009 to 2019 patient-level adverse events data from the Medicare Patient Safety Monitoring System, a randomly selected medical records-abstracted patient safety database, to the 2005 to 2016 hospital-level HF-specific 30-day all-cause mortality and readmissions data from the United States Centers for Medicare & Medicaid Services. Hospitals were classified to one of 3 performance categories based on their risk-standardized 30-day all-cause mortality and readmission rates: better (both in <25th percentile), worse (both >75th percentile), and average (otherwise). Our main outcome was the occurrence (yes/no) of one or more adverse events during hospitalization. A mixed-effect model was fit to assess the relationship between a patient's risk of having adverse events and hospital performance categories, adjusted for patient and hospital characteristics.

RESULTS

The study included 39 597 patients with HF from 3108 hospitals, of which 252 hospitals (8.1%) and 215 (6.9%) were in the better and worse categories, respectively. The rate of patients with one or more adverse events during a hospitalization was 12.5% (95% CI, 12.1-12.8). Compared with patients admitted to better hospitals, patients admitted to worse hospitals had a higher risk of one or more hospital-acquired adverse events (adjusted risk ratio, 1.24 [95% CI, 1.06-1.44]).

CONCLUSIONS

Patients admitted with HF to hospitals with high 30-day all-cause mortality and readmission rates had a higher risk of in-hospital adverse events. There may be common quality issues among these 3 measure concepts in these hospitals that produce poor performance for patients with HF.

Enhanced Recovery After Surgery (ERAS) Protocols for Improving Outcomes for Patients Undergoing Major Colorectal Surgery

Enhanced Recovery After Surgery (ERAS) protocols have gained recognition as a perioperative care approach for patients undergoing major colorectal surgery. This systematic review aims to evaluate the effects of ERAS protocols on outcomes in this patient population. A systematic search was conducted in PubMed, Cochrane Library, and Embase databases for studies published between January 2010 and September 2021. Inclusion criteria encompassed studies assessing the impact of ERAS protocols on patients undergoing major colorectal surgery. Data were extracted, and a qualitative synthesis of the included studies was performed. A total of 18 studies met the inclusion criteria. The implementation of ERAS protocols was associated with several positive outcomes. Compared to traditional care, ERAS protocols significantly reduced the length of hospital stay (mean difference [MD]: -1.64 days, 95% confidence interval [CI]: -2.21 to -1.08, p<0.00001), postoperative complications (odds ratio [OR]: 0.57, 95% CI: 0.46 to 0.71, p<0.00001), and readmission rates (OR: 0.57, 95% CI: 0.38 to 0.85, p=0.006). ERAS protocols also led to a shorter time to return of bowel function (MD: -0.74 days, 95% CI: -1.03 to -0.45, p<0.00001), time to first mobilization (MD: -0.55 days, 95% CI: -0.82 to -0.28, p<0.0001), and time to first oral intake (MD: -0.62 days, 95% CI: -0.95 to -0.28, p=0.0003). Additionally, patients reported higher satisfaction levels with the implementation of ERAS protocols (MD: 1.02, 95% CI: 0.19 to 1.86, p=0.02). This systematic review demonstrates that the implementation of ERAS protocols in major colorectal surgery is associated with improved outcomes. ERAS protocols lead to reduced hospital stays, lower postoperative complications, and decreased readmission rates. Furthermore, they facilitate faster recovery of bowel function, mobilization, and oral intake. Patients also express higher satisfaction levels with ERAS implementation. Healthcare providers should consider adopting ERAS protocols to optimize perioperative care in patients undergoing major colorectal surgery.

Early readmissions of spontaneous bacterial peritonitis in the USA: Insights into an emerging challenge

BACKGROUND AND AIM

Early readmissions of spontaneous bacterial peritonitis (SBP) are often associated with poor outcomes. We compared characteristics and outcomes for index and 30-day readmissions of SBP in the USA.

METHODS

We analyzed the Nationwide Readmissions Database for 2018 to identify all adult (≥ 18 years) 30-day readmissions of SBP in the USA. Hospitalization characteristics and outcomes for index and 30-day readmissions of SBP were compared. Independent predictors of 30-day readmissions were also identified.

RESULTS

In 2018, of the 5,797 index admissions for SBP, 30% (1726) were readmitted within 30 day. At the time of readmission, the most common admitting diagnosis was alcoholic cirrhosis of the liver with ascites (11.8%) followed by sepsis due to an unspecified organism (9.2%). SBP as an admitting diagnosis was identified for only 8.3% of these 30-day readmissions. Compared with index admissions, 30-day readmissions of SBP had a lower mean age (56.1 vs 58.6 years, P < 0.001) without a statistically significant difference for gender. Furthermore, 30-day readmissions of SBP were associated with significantly higher odds of inpatient mortality (10% vs 4.9%, OR: 2.15, 95% CI: 1.66-2.79, P < 0.001), and mean total hospital charge ($85,031 vs $56,000, mean difference: 29,032, 95% CI: 12,867-45,197, P < 0.001) compared with index admissions. The presence of chronic pulmonary disease, liver failure, inpatient dialysis, and discharge against medical advice were identified as independent predictors for increased 30-day readmissions of SBP.

CONCLUSION

The 30-day readmission rate of SBP was 30% and these readmissions were associated with higher odds of inpatient mortality compared with index admissions.

The Association of Attending Physicians' Publications and Patients' Readmission Rates: Evidence from Tertiary Hospitals in China Using a Retrospective Data Analysis

BACKGROUND

Physicians play a unique role in scientific and clinical research, which is the cornerstone of evidence-based medical practice. In China, tertiary public hospitals link promotions and bonuses with publications. However, the weight placed on research in the clinician's evaluation process and its potential impact on clinical practice have come under controversy. Despite the heated debate about physicians' role in research, there is little empirical evidence about the relationship between physicians' publications and their clinical outcomes.

METHOD

This paper examines the association of the quantity and quality of tertiary hospitals' attending physicians' publications and inpatient readmission rates in China. We analyzed a 20% random sample of inpatient data from the Urban Employee Basic Medical Health Insurance scheme in one of the largest cities in China from January 2018 through October 2019. We assessed the relationship between the quantity and impact factor of physicians' publications and 30-day inpatient readmission rates using logistic regression. There were 111,965 hospitalizations treated by 5794 physicians in our sample.

RESULTS

Having any first-author publications was not associated with the rate of readmission. Among internists, having clinical studies published in journals with an average impact factor of 3 or above was associated with lower readmission rates (OR = 0.849; 95% CI (0.740, 0.975)), but having basic science studies published in journals with an average impact factor of 3 or above was not associated with the rate of readmission. Among surgeons, having clinical studies published in journals with an average impact factor of 3 or above was likewise associated with lower readmission rates (OR = 0.708 (0.531, 0.946)), but having basic science studies published in journals with an average impact factor of 3 or above was associated with higher readmission rates (OR = 1.230 (1.051, 1.439)).

Incontinence and Incontinence-Associated Dermatitis in Acute Care: A Retrospective Analysis of Total Cost of Care and Patient Outcomes From the Premier Healthcare Database

PURPOSE

To evaluate the prevalence of incontinence and treatment of incontinence-associated dermatitis (IAD) and associations with outcomes including total cost of care, length of stay (LOS), 30-day readmission, sacral area pressure injuries present on admission and hospital acquired pressure injuries, and progression of all sacral area pressure injuries to a higher stage.

DESIGN

Retrospective analysis.

SUBJECTS AND SETTINGS

Data were retrieved from the Premier Healthcare Database and comprised more than 15 million unique adult patient admissions from 937 hospitals. Patients were 18 years or older and admitted to a participating hospital between January 1, 2016, and December 31, 2019.

METHODS

Given the absence of an IAD International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code, we categorized patients treated for IAD by selecting patients with a documented incontinence ICD-10-CM code and a documented charge for dermatology products used to treat IAD. The t test and χ2 tests determined whether incontinence and treatment for IAD were associated with outcomes.

RESULTS

Incontinence prevalence was 1.5% for the entire sample; prevalence rate for IAD among incontinent patients was 0.7%. As compared to continent patients, incontinent patients had longer LOS (6.4 days versus 4.4 days), were 1.4 times more likely to be readmitted, 4.7 times more likely to have a sacral pressure injury upon admission pressure injury, 5.1 times more likely to have a sacral hospital-acquired pressure injury, and 5.8 times more likely to have a sacral pressure injury progress to a severe stage. As compared to incontinent patients without IAD treatment, those with IAD treatment had longer LOS (9.7 days versus 6.4 days), were 1.3 times more likely to be readmitted, and were 2.0 times more likely to have a sacral hospital-acquired pressure injury. Total index hospital costs were 1.2 times higher for incontinent patients and 1.3 times higher for patients with IAD treatment.

CONCLUSIONS

Incontinence and IAD prevalence are substantially lower than past research due to underreporting of incontinence. The lack of an ICD-10-CM code for IAD further exacerbates the underreporting of IAD. Despite low prevalence numbers, our results show higher health care costs and worse outcomes for incontinent patients and patients with IAD treatment.

Post-Trauma Follow-up Phone Call Shows Lower Readmission Rates for Patients Discharged From Emergency Department Compared to Inpatient Stay

BACKGROUND

Studies show follow-up phone calls decrease readmission rates (RR) in trauma patients and social vulnerabilities may play a role as well. Minimal literature exists comparing RR of trauma patients who required an inpatient stay to those whose treatment was limited to the Emergency Department (ED), as they are at high risk of recidivism. We hypothesized post-trauma follow-up calls would show higher RR for ED patients than those requiring inpatient stay, as well as potentially differing outcomes for minorities.

STUDY DESIGN

A retrospective analysis from 2019-2020 of 1328 trauma patients from UCI Medical Center, discharged from inpatient facilities or the ED. A questionnaire script read by a nurse practitioner to patients via phone call following discharge. Data associated with readmission were captured. Multivariable logistic regression analysis was performed, controlling for patient factors including severity of injury.

RESULTS

Patients discharged from the ED were 47.4% less likely to be readmitted than those who required an inpatient stay (P < .01). However, ED patients were 88.7% less likely to receive a prescription than inpatient stay patients (P < .01). No difference between ED and inpatient discharge contact rates was noted (P < .99). Furthermore, no difference in readmission rates was noted for minorities.

CONCLUSION

Post-trauma follow-up calls showed lower RR for index ED visit patients than those requiring inpatient stay, contrary to expectations. However, ED visit patients were also less likely to receive/fill prescriptions compared to those requiring inpatient stay. Ongoing analysis is warranted to further validate and improve follow-up call programs to ensure equitable health care.

A Retrospective Study of Admission NT-proBNP Levels as a Predictor of Readmission Rate, Length of Stay and Mortality

Introduction

Serum levels of pro-B-type natriuretic peptide (BNP) and N-terminal (NT) proBNP are measured at admission to assess the likelihood of acutely decompensated heart failure (ADHF). Elevated NT-proBNP levels on initial presentation are a reliable marker of ADHF. However, the prognostic significance of NT-proBNP levels measured on admission remains unknown. With a better understanding of how admitting NT-proBNP levels impacts readmission rates, length of stay and mortality, future prospective studies with specific interventions can be developed to reduce all-cause readmissions, shorten length of stay and reduce mortality.

Methods

In this retrospective study, we evaluated heart failure with reduced ejection fraction (HFrEF) admissions from 2017-2018 with a focus on 30-, 60- and 90-day all-cause readmissions, length of stay (LOS) and in-hospital mortality rate that are predicted by NT-proBNP levels measured on admission. Using the HCA Healthcare Enterprise Data Warehouse, adult patients age 18 to 75 were selected using admission ICD-10 codes for HFrEF. Dialysis patients were excluded. Our search of 90 hospitals yielded 21,445 patients who were stratified into quartiles depending on their admission NT-proBNP levels: group 1 (<1669 pg/ml), group 2 (1670-4274 pg/ml), group 3 (4275-10,499 pg/ml) and group 4 (>10,500 pg/ml).

Results

Readmission Rates: The 60-day all-cause readmission was significantly (p = 0.047) higher in group 4 compared to group 1 (adjusted odds ratio (OR) = 1.116, p = 0.013) and group 2 (adjusted OR = 1.111, p = 0.014). The 90-day all cause readmission for group 4 was also significantly higher when compared to group 1 (adjusted OR = 1.105, p = 0.021).Length of Stay: Elevated NT-proBNP concentrations were associated with a significantly longer LOS (p <0.0005). Pairwise, comparisons and estimates for adjusted LOS showed a positive linear association between higher NT-proBNP groups and longer LOS.Mortality: Higher inpatient mortality rates were associated with elevated NT-proBNP levels. The mortality rate was 0.9% in group 1 compared to a 4.7% mortality rate in group 4. Adjusted OR for mortality increased with increasing levels of NT-proBNP.

Conclusions

Based on the analysis, higher admitting NT-proBNP levels were associated with significantly higher 60-day all-cause readmission, longer LOS and increased mortality. These findings suggest that measuring NT-proBNP levels at admission may provide an indication of patient outcomes. Prospective studies with targeted strategies can be developed to reduce readmissions, shorten LOS and reduce mortality based on admission NT-proBNP levels.

Hospitalization, Asthma Phenotypes, and Readmission Rates in Pre-school Asthma

Objective: Children with pre-school asthma suffer disproportionally more often from severe asthma exacerbations with emergency visits and hospital admissions compared to school children. Despite this high disease burden, there are only a few reports looking at this particular severe asthma cohort. Similarly, there is little real-life research on the distribution of asthma phenotypes and personalized treatment at discharge in this age group. Patients and Methods: Retrospective analysis of the electronic charts of all children aged 1-5 years with asthma hospitalizations (ICD J45) at the Frankfurt University between 2008 and 2017. An acute severe asthma exacerbation was defined as dyspnea, oxygen demand, and/or systemic steroid therapy. Age, gender, duration of hospitalization, asthma phenotype, treatment, and readmission rate were analyzed. Results: Of 572 patients, 205 met the definition of acute severe asthma. The phenotypic characterization showed 56.1% had allergic asthma, 15.2% eosinophilic asthma and 28.7% non-allergic asthma. Of these patients, 71.7% were discharged with inhaled corticosteroids (ICS) or ICS + long-acting-beta-agonists (LABA), 15.1% with leukotriene antagonists (LTRA) and 7.3% salbutamol on demand. The rate of emergency presentations (emergency department and readmission) within 12 months after discharge was high (n = 42; 20.5%). No phenotype tailored treatment was detectable. Neither the number of eosinophils (>300/μl) nor the treatment at discharge had an effect on emergency visits and readmission rate. Conclusion: Despite protective therapy with ICS, ICS + LABA, or LTRA, the readmission rate was high. Thus, current care and treatment strategies should be reevaluated continuously, in order to better control asthma in pre-school children and prevent hospitalization.

Patient length of stay, patient readmission rates and the provision of professional interpreting services in healthcare in Australia

Linguistic and ethnic diversity is a feature of patient profiles at almost all public healthcare facilities in urban areas in Australia. Patients with limited proficiency in the socially dominant language - in this case Limited English proficiency (LEP) patients - commonly form a significant patient group in public healthcare settings. Communication barriers that exist between patients and healthcare professionals necessitate the provision of translation and interpreting (T&I) services. This study presents longitudinal data from Melbourne, Australia, on the provision of (T&I) services together with patient length of stay (LOS) and patient readmission rates over a 10-year period at a large, public healthcare provider. Patient LOS and patient readmission rates are key metrics for effective diagnosis and treatment of patients and commonly used to measure the performance of various aspects of healthcare provision. The augmentation of T&I services within a general policy of patient-centred care is shown to accompany decreased LOS and lower readmission rates for LEP patients.

Factors Associated With Extended Length of Stay and 90-Day Readmission Rates Following ACDF

STUDY DESIGN

Retrospective.

OBJECTIVE

Identify patient risk factors for extended length of stay (LOS) and 90-day hospital readmissions following elective anterior cervical discectomy and fusion (ACDF).

METHODS

Included ACDF patients from 2013 to 2017 at a single institution. Eligible patients were subset into LOS <2 and LOS ≥2 days, and no 90-day hospital readmission and yes 90-day hospital readmission. Patient and surgical factors were compared between the LOS and readmission groups. Multivariable logistic regression analysis was utilized to determine the association of independent factors with LOS and 90-day readmission rates.

RESULTS

Our sample included 1896 patients; 265 (14%) had LOS ≥2 days, and 121 (6.4%) had a readmission within 90 days of surgery. Patient and surgical factors associated with LOS included patient age ≥65 years (odds ratio [OR] 1.72, 95% confidence interval [CI] 1.15-2.56), marriage (OR 0.57, 95% CI 0.43-0.79), private health insurance (OR 0.28, 95% CI 0.15-0.50), American Society of Anesthesiologists (ASA) score (OR 1.52, 95% CI 1.12-1.86), African American race (OR 1.95, 95% CI 1.38-2.72), and harvesting iliac crest autograft (OR 4.94, 95% CI 2.31-10.8). Patient and surgical factors associated with 90-day hospital readmission included ASA score (OR 1.81, 95% CI 1.32-2.49), length of surgery (OR 1.002, 95% CI 1.001-1.004), and radiculopathy as indication for surgery (OR 0.60, 95% CI 0.39-0.96).

CONCLUSIONS

Extended LOS and 90-day hospital readmissions may lead to poorer patient outcomes and increased episode of care costs. Our study identified patient and surgical factors associated with extended LOS and 90-day readmission rates. In general, preoperative patient factors affected these outcomes more than surgical factors.

Patients Who Have Cannabis Use Disorder Have Higher Rates of Venous Thromboemboli, Readmission Rates, and Costs Following Primary Total Knee Arthroplasty

BACKGROUND

Studies have shown that cannabis can interfere with hematological parameters and platelet morphology. The purpose of this study is to investigate whether patients with cannabis use disorder undergoing primary total knee arthroplasty (TKA) have higher rates of (1) venous thromboemboli (VTEs); (2) readmissions; and (3) costs.

METHODS

Study group patients undergoing primary TKA were identified from a large, nationwide database. Patients who had a history of VTEs, deep vein thromboses (DVTs), pulmonary emboli (PEs), and coagulopathies before their TKA were excluded. Study group patients were matched to controls in a 1:4 ratio by age, sex, a comorbidity index, and medical comorbidities. The query yielded 18,388 patients (cannabis = 3680; controls = 14,708). Outcomes analyzed included rates of 90-day VTEs, DVTs, and PEs, in addition to 90-day readmissions and costs. A P value less than .01 was considered statistically significant.

RESULTS

Patients who have cannabis use disorder were found to have significantly higher incidence and odds (2.79% vs 1.78%; odds ratio [OR], 1.58; P < .0001) of VTEs, DVTs (2.41% vs 1.44%; OR, 1.68; P < .0001), and PEs (0.97% vs 0.62%; P = .01). Readmissions were significantly higher (27.03% vs 23.18%; OR, 1.22; P < .0001) in patients who have cannabis use disorder. Patients with cannabis use disorder have significantly higher day of surgery ($14,024.88 vs $12,127.49; P < .0001) and 90-day costs ($19,155.45 vs $16,315.00; P < .0001).

CONCLUSION

This study found that patients who have a cannabis use disorder have higher rates of thromboembolic complications, readmission rates, and costs following primary TKA compared to a matched cohort.

Readmission Rates and Their Impact on Hospital Financial Performance: A Study of Washington Hospitals

This longitudinal study examines whether readmission rates, made transparent through Hospital Compare, affect hospital financial performance by examining 98 hospitals in the State of Washington from 2012 to 2014. Readmission rates for acute myocardial infarction (AMI), pneumonia (PN), and heart failure (HF) were examined against operating revenues per patient, operating expenses per patient, and operating margin. Using hospital-level fixed effects regression on 276 hospital year observations, the analysis indicated that a reduction in AMI readmission rates is related with increased operating revenues as expenses associated with costly treatments related with unnecessary readmissions are avoided. Additionally, reducing readmission rates is related with an increase in operating expenses. As a net effect, increased PN readmission rates may show marginal increase in operating margin because of the higher operating revenues due to readmissions. However, as readmissions continue to happen, a gradual increase in expenses due to greater use of resources may lead to decreased profitability.

Benefit of a Stroke Management Program

Hospital participation in stroke bundle programs presents financial risk. There are limited comparative data on the success of such programs. The authors aimed to assess the success of a management program in reducing the number of patients admitted to a skilled nursing facility (SNF), average length of stay, and the number of patients discharged to inpatient rehabilitation units. Three program metrics included reduction in number of stroke patients admitted to SNF, reduction in length of stay at SNFs, and reduced 90-day hospital readmission rates. The program was implemented during a 3-year period from October 1, 2015, through September 30, 2018, included 803 patients in the data, and demonstrated financial gain with positive patient outcomes. There was a 0.5% reduction in the number of stroke patients admitted to SNF. Sending patients home with a high-quality home care agency for rehabilitation and navigation assistance were the goals for this metric. A 1.65-day reduction in length of stay for overall SNF providers was noted. This was achieved by utilizing a preferred network of skilled facilities and community partners that the nurse navigator interfaced with weekly. The proportion of patients discharged to inpatient rehabilitee units was 2.2% less than in the baseline years. With the implementation of a stroke nurse navigator, hospital readmissions as a percentage of admissions for stroke decreased by 4%. Overall return on investment was greater than 400% after accounting for additional staffing and data/license fees.

Defining readmissions among patients undergoing open reduction and internal fixation (ORIF) in claims database analyses

Objective: To evaluate the impact of using different readmissions definitions among patients undergoing open reduction and internal fixation (ORIF) of the femur, tibia, and fibula in claims databases.Methods: Patients from the IBM MarketScan Research Commercial and Medicare Databases receiving inpatient ORIF between 1 January 2010 and 31 January 2017 (index) were identified. Readmissions within 90 days were calculated starting from the index day of discharge to 2 days after discharge. Readmission rates were also reported after accounting for records for rehabilitation, aftercare, or transfer using discharge status, provider type, and Diagnosis Related Group (DRG) codes. For patients with "transferred" as the index hospitalization discharge status, readmissions were calculated 2 days after discharge.Results: A total of 82,692 patients with ORIF for femur, tibia or fibula were identified; mean (SD) age was 60.1 (23.1) years and nearly two-thirds were female (62.3%). For the index hospitalization, 41.6% patients had "transferred" as the discharge status. The readmission rate calculated from the same day as the discharge was 14.7%. Readmission rates calculated 1 and 2 days after index discharge were 8.5 and 7.7%. After accounting for rehabilitation, aftercare and transfer, the corrected readmission rate was 8.6%. Corrected readmission rates calculated 1 and 2 days after index discharge were 7.2 and 7.2%, respectively. The most common diagnosis associated with same day readmission was rehabilitation, whereas that was not observed with readmissions 1 and 2 days after discharge.Conclusions: The accuracy of identifying true admissions was improved by defining readmissions as occurring after the day of discharge and by accounting for rehabilitation, aftercare, and transfer.

The Impact Of Pharmaceutical Interventions On The Use Of Carbapenems In A Chinese Hospital: A Pre-Post Study

Background

The challenge of drug resistance to carbapenems is of international concern with leading to increased hospital lengths of stay, costs, and mortality rates. How to get rid of the vicious cycle of drug resistance, new drugs, and re-resistance, and even the emergence of all-drug-resistant bacteria that humans cannot cope with, are the major challenges we face. To date, data about pharmaceutical interventions on the use of carbapenems are currently limited.

Patients and methods

A retrospective cohort study was conducted to compare pre- and post-intervention in Tongde Hospital of Zhejiang Province. Pharmaceutical interventions were performed in the post-intervention group, including real time monitoring of medication orders, educative group activities, and making interventions to physicians. Intervention acceptance and outcomes, including the length of hospital stay, readmission rates, 30-day mortality, and utilization of carbapenems, which was evaluated by the daily defined doses (DDDs), the days of therapy (DOTs), and the cost of carbapenems, were reviewed.

Results

During the study, 593 interventions were provided by clinical pharmacists with an average acceptance rate of 82.79%. Compared with the pre-intervention group, prescriptions of carbapenems for pathogen-directed therapy were improved significantly in the post-intervention group (59.27% vs 21.74%, p=0.022). The DDDs decreased from 281.96 to 174.28 and DOTs decreased from 9.19 to 5.18 after pharmaceutical intervention, and the pharmaceutical interventions had significantly lower mean total cost of carbapenems ($13,828.8 vs $8137.1, p=0.004) and length of hospital stay (9.3±1.5 vs 15.9±2.2, p=0.014). There was a significant reduction in 30-day mortality in the post-intervention group (9.46% vs 17.86%, p=0.013) while there were no differences found in the 30-day readmission (20.19% vs 20.66%, p=0.99).

Conclusion

Implementation of pharmaceutical interventions in our hospital successfully improved the appropriateness of carbapenem prescribing overall, and reduced the DDDs, DOTs, length of hospital day, and cost of carbapenems.

Changes in coding of pneumonia and impact on the Hospital Readmission Reduction Program

OBJECTIVE

To evaluate whether changes in diagnosis assignment explain reductions in 30-day readmission for patients with pneumonia following the Hospital Readmission Reduction Program (HRRP).

DATA SOURCES

100 percent MedPAR, 2008-2015.

STUDY DESIGN

Retrospective cohort study of Medicare discharges in HRRP-eligible hospitals. Outcomes were 30-day readmission rates for pneumonia under a "narrow" definition (used for the HRRP until October 2015; n = 2 288 644) and a "broad" definition that included certain diagnoses of sepsis and aspiration pneumonia (used since October 2015; n = 3 618 215). We estimated changes in 30-day readmissions in the pre-HRRP period (January 2008-March 2010), the HRRP implementation period (April 2010-September 2012), and the HRRP penalty period (October 2012-June 2015).

PRINCIPAL FINDINGS

Under the narrow definition, adjusted annual readmission rates changed by +0.07 percentage points (pp) during the pre-HRRP period (95% CI: -0.03 pp, +0.18 pp), -1.07 pp during HRRP implementation (95% CI: -1.15 pp, -0.99 pp), and -0.09 pp during the penalty period (95% CI: -0.18 pp, -0.00 pp). Under the broad definition, 30-day readmissions changed by +0.21 pp during the pre-HRRP period (95% CI: +0.12 pp, +0.30 pp), -1.28 pp during HRRP implementation (95% CI: -1.35 pp, -1.21 pp), and -0.09 pp during the penalty period (95% CI: -0.16 pp, -0.02 pp).

CONCLUSIONS

Changes in the coding of inpatient pneumonia admissions do not explain readmission reduction following the HRRP.

Effects of Pharmacist-Conducted Medication Reconciliation at Discharge on 30-Day Readmission Rates of Patients With Chronic Obstructive Pulmonary Disease

PURPOSE

To analyze effect of pharmacist-conducted medication reconciliation on 30-day readmission rates in chronic obstructive pulmonary disease (COPD) and identify common medication errors among patient with readmissions.

METHODS

Pharmacists were educated on discharge medication reconciliation for patients with COPD. A retrospective chart review was conducted on patients who underwent pharmacist-conducted discharge medication reconciliation to determine 30-day readmissions. Medication errors analyzed included medication omissions and dose or frequency errors. Previously collected internal research without pharmacist-conducted medication reconciliation served as the control.

RESULTS

There were 65 patients in the control group and 50 in the intervention group. About 25% of patients in the control group and 26% of patients in the intervention group had any cause readmissions within 30 days of discharge (P = .87). Both the control and the intervention group had similar COPD-related readmissions of 12.3% and 12.6%, respectively. Medication dose or frequency errors consisted of 68.9% and 46.7% of total errors in the control and the intervention groups, respectively. Long-acting muscarinic antagonist (LAMA) or long-acting beta 2-agonist (LABA) were the most common drug classes to be incorrectly dosed or omitted at discharge. In the intervention group, 30 errors were identified. Due to inability to coordinate discharges, pharmacists intervened on 13 errors, 7 of which were accepted by the prescriber.

CONCLUSION

Pharmacist-conducted medication reconciliation at discharge did not affect 30-day readmission rates of patients with COPD. Confounding factors included a small sample size, passive pharmacist education, and discharge issues. The most common medication errors at discharge were dosing or frequency errors of LABAs or LAMAs.

Reduction in Hospitals' Readmission Rates: Role of Hospital-Based Skilled Nursing Facilities

Hospital readmission within 30 days of discharge is an important quality measure given that it represents a potentially preventable adverse outcome. Approximately, 20% of Medicare beneficiaries are readmitted within 30 days of discharge. Many strategies such as the hospital readmission reduction program have been proposed and implemented to reduce readmission rates. Prior research has shown that coordination of care could play a significant role in lowering readmissions. Although having a hospital-based skilled nursing facility (HBSNF) in a hospital could help in improving care for patients needing short-term skilled nursing or rehabilitation services, little is known about HBSNFs' association with hospitals' readmission rates. This study seeks to examine the association between HBSNFs and hospitals' readmission rates. Data sources included 2007-2012 American Hospital Association Annual Survey, Area Health Resources Files, the Centers for Medicare and Medicaid Services (CMS) Medicare cost reports, and CMS Hospital Compare. The dependent variables were 30-day risk-adjusted readmission rates for acute myocardial infarction (AMI), congestive heart failure, and pneumonia. The independent variable was the presence of HBSNF in a hospital (1 = yes, 0 = no). Control variables included organizational and market factors that could affect hospitals' readmission rates. Data were analyzed using generalized estimating equation (GEE) models with state and year fixed effects and standard errors corrected for clustering of hospitals over time. Propensity score weights were used to control for potential selection bias of hospitals having a skilled nursing facility (SNF). GEE models showed that the presence of HBSNFs was associated with lower readmission rates for AMI and pneumonia. Moreover, higher SNFs to hospitals ratio in the county were associated with lower readmission rates. These findings can inform policy makers and hospital administrators in evaluating HBSNFs as a potential strategy to lower hospitals' readmission rates.

Identifying Risk Factors for 30-Day Readmissions After Triple Arthrodesis Surgery

Rigid flatfoot deformity is a debilitating condition that can be managed by triple arthrodesis surgery. Triple arthrodesis has the potential to restore health-related quality of life, but it is also associated with several complications. Few studies have examined the 30-day readmission rates after triple arthrodesis. The objective of this study was to investigate risk factors for 30-day all-cause readmissions after triple arthrodesis. The nationwide readmission database was queried from 2013. By using International Classification of Disease, Ninth Revision, procedure codes, all triple arthrodesis procedures were identified. Demographic factors, comorbidities, insurance status, and hospital characteristics were statistically compared between patients who experienced a 30-day readmission and those who did not. Multivariable logistic regression was used to identify independent risk factors for 30-day readmission. Overall, 1916 triple arthrodesis cases were identified. The overall 30-day readmission rate after triple arthrodesis was 4.6%. Univariate analysis revealed a statistically higher proportion of patients with electrolyte abnormalities (13.8% vs 4.6%; p < .01) in the patients who were readmitted within 30 days compared with those who were not. Multivariable analysis demonstrated Medicaid insurance, relative to private insurance, as the only statistically significant predictor of 30-day readmission with an odds ratio of 4.43 (p < .05). These results suggest that patients of lower socioeconomic status may be at a greater risk for development of a short-term readmission after triple arthrodesis surgery. These findings are important for surgeon and patient communication, counseling, and postoperative care when choosing to pursue triple arthrodesis surgery.

Patient Handoff Processes: Implementation and Effects of Bedside Handoffs, the Teach-Back Method, and Discharge Bundles on an Inpatient Oncology Unit

BACKGROUND

Bedside handoffs, the teach-back method, and discharge bundles have been shown to contribute to empowering patients to actively engage in their treatment.

OBJECTIVES

The objectives were to identify patient activation scores, patient readmission rates, and nursing staff satisfaction before and after implementing bedside handoffs, the teach-back method, and discharge bundles on an inpatient oncology unit at a large military treatment facility.

METHODS

A series of three cycles using the Plan-Do-Study-Act framework guided implementation of the multifaceted approach. Patient activation scores, readmission rates, staff satisfaction, and anecdotal feedback from patients and nursing staff were collected prior to and following implementation.

FINDINGS

The sample of patients with cancer had high patient activation scores. After implementation of the multifaceted approach, readmission rates decreased from 32% to 25%, and staff satisfaction improved.

National trends in emergency readmission rates: a longitudinal analysis of administrative data for England between 2006 and 2016

OBJECTIVE

To assess trends in 30-day emergency readmission rates across England over one decade.

DESIGN

Retrospective study design.

SETTING

150 non-specialist hospital trusts in England.

PARTICIPANTS

23 069 134 patients above 18 years of age who were readmitted following an initial admission (n=62 584 297) between April 2006 and February 2016.

PRIMARY AND SECONDARY OUTCOMES

We examined emergency admissions that occurred within 30 days of discharge from hospital ('emergency readmissions') as a measure of healthcare quality. Presented are overall readmission rates, and disaggregated by the nature of the indexed admission, including whether it was elective or emergency, and by clinical health condition recorded. All rates were risk-adjusted for patient age, gender, ethnicity, socioeconomic status, comorbidities and length of stay.

RESULTS

The average risk-adjusted, 30-day readmission rate increased from 6.56% in 2006/2007 to 6.76% (P<0.01) in 2012/2013, followed by a small decrease to 6.64% (P<0.01) in 2015/2016. Emergency readmissions for patients discharged following elective procedures decreased by 0.13% (P<0.05), whereas those following emergency admission increased by 1.27% (P<0.001). Readmission rates for hip or knee replacements decreased (-1.29%; P<0.001); for acute myocardial infarction (-0.04%; P<0.49), stroke (+0.62%; P<0.05), chronic obstructive pulmonary disease (+0.41%; P<0.05) and heart failure (+0.15%; P<0.05) remained stable; and for pneumonia (+2.72%; P<0.001), diabetes (+7.09%; P<0.001), cholecystectomy (+1.86%; P<0.001) and hysterectomy (+2.54%; P<0.001) increased.

CONCLUSIONS

Overall, emergency readmission rates in England remained relatively stable across the observation period, with trends of slight increases contained post 2012/2013. However, there were large variations in trends across clinical areas, with some experiencing marked increases in readmission rates. This highlights the need to better understand variations in outcomes across clinical subgroups to allow for targeted interventions that will ensure highest standards of care provided for all patients.

Identifying Cognitive Impairment in Hospitalized Older Adults to Prevent Readmission: Two Case Studies

OBJECTIVE

To describe two patient outcomes post-discharge from an acute hospital admission. Both patients underwent cognitive testing during hospitalization.

METHODS

A battery of cognitive tests was administered to two hospitalized older adult patients. Both patients were evaluated in their homes within 72 hours of discharge and again at 14- and 30-days by a nurse practitioner.

RESULTS

One of the patients was readmitted within 30 days of hospital discharge due to complications from an amputation. This patient did not perform well on cognitive measures which may have been related to his pain levels and/or his medication regimen.

CONCLUSIONS

Not all readmissions are avoidable; however, if readmissions are related to cognitive impairment, implementing strategies tailored to this population may reduce readmission rates.

CLINICAL IMPLICATIONS

Risk factors for readmission should be identified so the discharge team can develop a tailored plan of care. Including both the patient and an informal caregiver may reduce the chance of a hospital readmission in older adults with cognitive impairment regardless of the etiology.

Impact of an inpatient geriatric consultative service on outcomes for cognitively impaired patients

BACKGROUND

Impact of geriatric consultative services (GCS) on hospital readmission and mortality outcomes for cognitively impaired (CI) patients is not known.

OBJECTIVE

Evaluate impact of GCS on hospital readmission and mortality among CI inpatients.

DESIGN

Secondary data analysis of a prospective trial of a computerized decision support system between July 1, 2006 and May 30, 2008.

SETTING

Study conducted at Eskenazi hospital, Indianapolis, Indiana, a 340-bed, public hospital with over 2300 yearly admissions of patients ages 65 years or older.

PATIENTS

There were 415 inpatients aged 65 years and older with CI enrolled from July 2006 to March 2008.

MEASUREMENTS

Thirty-day and 1-year mortality and hospital readmission following the index admission. Cox proportional hazard models were used to determine the association between receiving GCS, readmission, or mortality while adjusting for demographics, discharge destination, delirium, Charlson Comorbidity Index, and prior hospitalizations. The propensity score method was used to adjust for the nonrandom assignment of GCS.

RESULTS

Patients receiving GCS were older (79 years old, 8.1 standard deviation [SD] vs 76 years old, 7.8 SD; P < 0.001) with higher incidence of delirium (49% vs 29%; P < 0.001). No significant differences were found between the groups for hospital readmission (hazard ratio [HR] = 1.19; 95% confidence interval = 0.89-1.59) and mortality at 12 months of index admission (HR = 0.91; 95% confidence interval = 0.59-1.40). However, a significant increase in readmissions was observed for the GCS group (HR = 1.75; 95% confidence interval = 1.06-2.88) at 30 days postdischarge.

CONCLUSION

One-year postdischarge outcomes of CI patients who received GCS were not different from patients who did not receive the service. New models of care are needed to improve postdischarge readmission and mortality among hospitalized patients with CI.

The rise of assertive community interventions in South Africa: a randomized control trial assessing the impact of a modified assertive intervention on readmission rates; a three year follow-up

BACKGROUND

Many countries have over the last few years incorporated mental health assertive interventions in an attempt to address the repercussions of deinstitutionalization. Recent publications have failed to duplicate the positive outcomes reported initially which has cast doubt on the future of these interventions. We previously reported on 29 patients from a developing country who completed 12 months in an assertive intervention which was a modified version of the international assertive community treatment model. We demonstrated reduction in readmission rates as well as improvements in social functioning compared to patients from the control group. The obvious question was, however, if these outcomes could be sustained for longer periods of time. This study aims to determine if modified assertive interventions in an under-resourced setting can successfully maintain reductions in hospitalizations.

METHODS

Patients suffering from schizophrenia who met a modified version of Weidens' high frequency criteria were randomized into two groups. One group received a modified assertive intervention based on the international assertive community treatment model. The other group received standard care according to the model of service delivery in this region. Data was collected after 36 months, comparing readmissions and days spent in hospital.

RESULTS

The results demonstrated significant differences between the groups. Patients in the intervention group had significantly less readmissions (p = 0.007) and spent less days in hospital compared to the patients in the control group (p = 0.013).

CONCLUSION

Modified assertive interventions may be successful in reducing readmissions and days spent in hospital in developing countries where standard care services are less comprehensive. These interventions can be tailored in such a way to meet service needs and still remain affordable and feasible within the context of an under-resourced setting.

Measuring hospital quality using pediatric readmission and revisit rates

OBJECTIVE

To assess variation among hospitals on pediatric readmission and revisit rates and to determine the number of high- and low-performing hospitals.

METHODS

In a retrospective analysis using the State Inpatient and Emergency Department Databases from the Healthcare Cost and Utilization Project with revisit linkages available, we identified pediatric (ages 1-20 years) visits with 1 of 7 common inpatient pediatric conditions (asthma, dehydration, pneumonia, appendicitis, skin infections, mood disorders, and epilepsy). For each condition, we calculated rates of all-cause readmissions and rates of revisits (readmission or presentation to the emergency department) within 30 and 60 days of discharge. We used mixed logistic models to estimate hospital-level risk-standardized 30-day revisit rates and to identify hospitals that had performance statistically different from the group mean.

RESULTS

Thirty-day readmission rates were low (<10.0%) for all conditions. Thirty-day rates of revisit to the inpatient or emergency department setting ranged from 6.2% (appendicitis) to 11.0% (mood disorders). Study hospitals (n = 958) had low condition-specific visit volumes (37.0%-82.8% of hospitals had <25 visits). The only condition with >1% of hospitals labeled as different from the mean on 30-day risk-standardized revisit rates was mood disorders (4.2% of hospitals [n = 15], range of hospital performance 6.3%-15.9%).

CONCLUSIONS

We found that when comparing hospitals' performances to the average, few hospitals that care for children are identified as high- or low-performers for revisits, even for common pediatric diagnoses, likely due to low hospital volumes. This limits the usefulness of condition-specific readmission or revisit measures in pediatric quality measurement.

Impact of admission blood glucose level on outcomes in community-acquired pneumonia in older adults

BACKGROUND

Community-acquired pneumonia (CAP) is a common cause of morbidity and mortality in older adults. Although diabetes mellitus is a risk factor for pneumonia, the clinical impact of blood glucose level at the time of admission is not clear. Our goal was to examine the association between admission hyperglycemia and subsequent mortality, length of stay, and readmission outcomes in older adults with CAP.

METHODS

A retrospective observational study was conducted using hospital data for community-acquired pneumonia admissions in 857 persons from January 1, 2008 to December 31, 2010. We examined the effects of admission glucose level on mortality, length of stay, and 30 day readmission, adjusted for demographic factors and comorbidity.

RESULTS

The mean age of the sample was 64 years, and 51% of the subjects were female. Inpatient mortality occurred in 4.6% and the median length of stay was 5 days (interquartile range 3-9 days). Readmission within 30 days occurred in 17%. We found little impact of first glucose measures on in-hospital mortality (P = 0.94), length of stay (P = 0.95), and 30-day readmission (P = 0.56). Subjects 65 years and older trended towards higher in-hospital mortality. Older age, cancer, heart failure, and cirrhosis were associated with adverse outcomes.

CONCLUSION

Glucose level upon admission for community-acquired pneumonia was not associated with adverse outcomes within 30 days in older adults.

Medical home quality and readmission risk for children hospitalized with asthma exacerbations

OBJECTIVE

The medical home likely has a positive effect on outpatient outcomes for children with asthma. However, no information is available regarding the impact of medical home quality on health care utilization after hospitalizations. We sought to explore the relationship between medical home quality and readmission risk in children hospitalized for asthma exacerbations.

METHODS

We enrolled 601 children, aged 1 to 16 years, hospitalized for an acute asthma exacerbation at a single pediatric facility that captures >85% of all asthma admissions in an 8-county area. Caregivers completed the Parent's Perception of Primary Care (P3C), a Likert-based, validated survey. The P3C yields a total score of medical home quality and 6 subscale scores assessing continuity, access, contextual knowledge, comprehensiveness, communication, and coordination. Asthma readmission events were prospectively collected via billing data. Hazards of readmission were calculated by using Cox proportional hazards adjusting for chronic asthma severity and key measures of socioeconomic status.

RESULTS

Overall P3C score was not associated with readmission. Among the subscale comparisons, only children with lowest access had a statistically increased readmission risk compared with children with the best access. Subgroup analysis revealed that children with private insurance and good access had the lowest rates of readmission within a year compared with other combinations of insurance and access.

CONCLUSIONS

Among measured aspects of medical home in a cohort of hospitalized children with asthma, having poor access to a medical home was the only measure associated with increased readmission. Improving physician access for children with asthma may lower hospital readmission.

The impact of weekends on outcome for emergency patients

Levels of staffing and access to diagnostics at weekends are recognised to be significantly lower than on weekdays. It is unclear if subsequent inpatient mortality and readmission rates for acute medical admissions are increased for weekend admissions compared to those on a weekday. A large Canadian study demonstrated increased weekend mortality but does the Edinburgh healthcare model support these findings? This study analysed all hospital admissions in 2001 to the Royal Infirmary of Edinburgh for six predetermined diagnoses (total 3,244): chronic obstructive pulmonary disease, cerebrovascular accidents, pulmonary embolism, pneumonia, collapse and upper gastrointestinal bleed. We compared hospital mortality rates, readmission rates and hospital length of stay for weekend admissions as compared to those on a weekday. Weekend admission was not associated with significantly higher in-hospital mortality, readmission rates or increased length of stay compared to the weekday equivalent for any of the six conditions. The implementation of an acute medical admissions unit in the Royal Infirmary of Edinburgh, with consistent staffing levels and 24-hour access to diagnostics for the early phase of critical illness, may have helped address the discrepancy in care suggested by previous studies.
